Despite claims to the contrary, Apple may still have the lead not just in US smartphone market share but also in demand, Nielsen said today. As of October, the iPhone had 27.9 percent of share of those asked, which was not just ahead of Android's 22.7 percent but just ahead of RIM's 27.4 percent. Among those looking at smartphone upgrades, 30 percent were looking to buy an iPhone while Android was at 28 percent; just 13 percent were planning to get a BlackBerry, the study showed.
